Answer:
The sum of interior angles of given polygon is 900°
Step-by-step explanation:
A regular polygon is a n-sided figure with n sides and the length of all sides is same.
In the diagram, we have a polygon with 7 sides.
The formula given is used to calculate the sum of interior angles of a polygon

Here n is the number of sides of polygon
In the given polygon
n = 7
So,

Hence,
The sum of interior angles of given polygon is 900°
Answer:
24ft²
Step-by-step explanation:
divide up the shape:
big triangle:
(looking for base)
9.8²= 4² + b²
b = 8.95ft
(finding area)
0.5*8.95*4 = 17.9ft²
small triangle:
(looking for base)
12-8.95=3.05ft
(finding area)
0.5*3.05*4 = 6.1ft²
Whole Shape:
17.9+6.1 = 24ft²

Answer:
1. (7+3)/2
2. 6, 3
3. 5/6
4. 500, 4000
Step-by-step explanation:
1. We are adding 7 and 3 so use the plus sign, THEN we divide by 2
Because we are adding first, put parentheses
(7+3)/2
2. Nearest whole means whole number (so basically no decimal)
5.823 --> 6 (because 8 is closer to 10 than 0)
3.147 --> 3 (because 1 is closer to 0)
3. 1/3+1/2
Find a common difference, which is 6
Multiply to get 6
1/3*2= 2/6
1/2*3=3/6
3+2=5/6 (when adding keep denominator the same)
4. There are 100 centimeters in a meter
5*100= 500 centimeters
There are 1000 grams in a kilogram
4*1000= 4000 grams
Hope this helps, lemme know if somethings still unclear!!
